2Sergio is a bunny rabbit whose father lives in constant fear for his son's safety and spends long, grueling hours teaching him survival skills for the dangers that a small bunny would encounter in his day. Unfortunately, Sergio's father is unaware that he was preparing his son for the ultimate battle for life and death. Sergio became proficient in his skills, and many times he stared danger in the face, even challenging and outwitting it. Then one day, something that was so hideous, so deadly, spooked Sergio so much that he became afraid of his own shadow.
